With chorionic gonadotropin injections, most false positives on morning pregnancy tests will show up for about seven days, so 48 hours after running out the morning pregnancy test will show a false positive mark. Chorionic gonadotropin is used for the treatment of follicles that do not have the ability to be discharged normally after they have grown and matured, and when injected into the body, it can promote the rupture of the follicle, transform it into the corpus luteum, and increase the secretion of progesterone. This will increase the success rate of ovulation and increase the probability of conception. Most people will experience false positives for about a week after the injection, but each person’s body type is different, so there may be slight differences in the duration, but most of them are one week is a normal phenomenon, don’t worry. If you are planning to get pregnant while using the drug, it is best to test for conception within 15 days of intercourse, as this will have a higher accuracy rate.
